Thermo-Flo AX1X Flow Switch with Compact Flow Controller

•Solid state sensor• Suitable for corrosive fluids• Optional strobe available

Offered in liquid and gas sensor types, the general purpose flow switch package provides reliable no or low-flow detection of relatively clean non-coating media with a 16A compact flow controller for pump or process protection. Liquid examples includes water and sulfuric acid. The optional flash alarm brings attention to low-flow alarm conditions. Available in Polypropylene-Ryton® and PVDF, the short flow sensor is used in pipe or ducting from 1/2” to 1 1/2”, and the long flow sensor is used in 2” and up. The flow switch set point may be adjusted from 0.04 to 3 fps in liquids, or 1 to 90 fps in gases for low-flow control. The flow sensor is best applied in applications with relatively constant temperature.

Features of the Thermo-Flo Flow Switch include:

Rugged PP-Ryton® or PVDF sensor for corrosive liquids and gases

Fail-safe relay control of pumps or valves with 0-60 second delay

PP enclosure rated NEMA 4X with swivel base for conduit alignment

Optional strobe brings immediate attention to flow alarm conditions

Invert switch changes relay state from NO to NC without rewiring

Solid state sensor is not damaged by over-ranging flow velocities

Application:

A common problem with metering pumps in flow applications is the characteristic of the output flow. The pulsating flow makes it difficult for flow switches to get an accurate and consistent flow rate. Often flow switches will not work because they are not able to see a reliable flow output. The Flowline Pulse Point fitting is designed to stabilize the pulsing flow for the Thermo-Flo flow switch. The cylindrical chamber creates a mini-vortex that translates to a relatively constant flow. The Thermo-Flo flow switch will be able to read the flow and provide an accurate and low-cost flow switch. The Flowline Pulse Point fitting is ideal for use in metering pumpapplications.
